What is the keto diet?

The ketogenic or keto diet is a high fat, moderate protein and low carbohydrate diet.

• Low carbs, high fats: You have to cut down on your carb consumption and replace it with fats. Your body will start utilising fats as its primary source of energy instead of carbohydrates. This state of the body is called ketosis.
• Moderate protein: If you consume high amounts of protein, your body will convert it into glucose through a process called gluconeogenesis. Hence, make sure your protein consumption is moderate.
• Practice intermittent fasting: If you follow intermittent fasting along with a ketogenic diet, your body will get into the ketosis phase faster.
  
  

People often tend to confuse the keto diet with the Atkins diet. However, both are not the same as the Atkins diet is a high protein, low fat and low carbohydrates diet.

When you have shifted to a keto diet

No need to transition into keto slowly: The ultimate goal of the keto diet is to get your body into the ketosis phase. If you transition slowly, then it will take a lot of time for your body to adapt. So, do not transition slowly; directly shift to the keto diet.

Plan the diet and meals well: Meal planning becomes crucial because there are many food restrictions in a keto diet. Be mindful about what foods you stock up in your pantry. If you plan and prepare your meals and snacks well in advance, it will become easier to follow the plan.

Manage portion sizes: For a keto diet to be effective, you must constantly monitor the number of calories you consume and learn to manage the portion sizes.

Hydrate yourself: Since there is additional loss of fluids, hydrating yourself becomes crucial.

Take supplements: There are high chances of becoming deficient in some nutrients because you cut down on many foods. Consult your doctor if you need to take any supplements to compensate for it.

Limit eating outside: If you plan to eat in restaurants, you must find the ones that serve foods that fit in a keto diet.

Follow it for at least 3-4 months: Our body requires 3-6 weeks for completely transitioning into the ketosis phase. For achieving effective results, you need to do it for at least 3-4 months.

When you plan to stop the keto diet

Gradually introduce carbs to your diet: After following a keto diet, if you want to transition back to low fat, moderate protein and high carb diet, you must gradually increase the number of carbs in your diet. If you start eating a lot of carbs suddenly, your body may not process it well. You may experience bloating and gain too much weight suddenly.
